20 VarTarg Brass/Chamber Questions

[Dead Eye]

My apologies If this has already been covered but I could not find it in a search. Of course I am not very good at that so... I understand the issue with Lapua 221 brass being larger at the .200 datum line. My questions are:

1. If you have a 20 VarTarg chamber that is set up for the Remington brass will you run into the same issues with Norma or Nosler brass as you will with the Lapua brass?
2. If I form brass from 5.56 Lake City brass will I run into the same issues or will the only issue be reduced capacity?
3. If I use Remington, Norma or Nosler brass where should I stop with load development to keep from killing my brass?

Thank you in advance for any help you can give me.
Dave
